Abstract: A method and a corresponding system for localizing a vehicle using a digital map are described. In accordance with the method, the digital map assigns to the features one or a plurality of predetermined attributes, which are provided for characterizing possibly occurring actual changes in the features in comparison to the digital map existing at the moment. On the basis of the assigned attributes, probabilities relative to the changes are also determined, and the vehicle is localized in consideration of the determined probabilities.

Abstract: A method, a processing unit which carries out the method, and a system including the processing unit for updating a digital map for locating motor vehicles are provided. In the case of the method for updating a digital map for locating motor vehicles, surroundings information is detected by a vehicle for the purpose of updating the digital map and the detected surroundings information is compared to the surroundings information which is stored on the digital map. In this case, the vehicle is located on the digital map, which means that the location or position of the vehicle on the digital map is known. For the purpose of detecting the surroundings information, the vehicle is navigated along a first route, whose most recently carried out comparison of surroundings information dates back the longest as compared to at least one further optional route.

Abstract: A method and device for determining a first highly precise position of a vehicle. The method includes acquiring surrounding-area data values using at least one radar sensor of the vehicle, the surrounding-area data values representing a surrounding area of the vehicle; and determining a rough position of the vehicle as a function of the acquired surrounding area data values. In addition, the method includes determining surrounding-area feature data values as a function of the determined rough position of the vehicle, the surrounding-area feature data values representing at least one surrounding-area feature and a second highly precise position of the at least one surrounding-area feature; and determining the first highly precise position of the vehicle as a function of the at least one surrounding-area feature, according to predefined localization criteria, the first highly precise position of the vehicle being more precise than the rough position of the vehicle.

Abstract: A method for predicting a construction-related driving-route change of a driving route for a vehicle includes at least a step of reading in and a step of detecting. In the step of reading in, at least one image signal is read in, which represents an image, recorded by the vehicle, of a construction-site parameter in the environment of the driving route. In the step of detecting, the impending driving-route change is detected using the image signal.

Abstract: A method for validating a digital map for a vehicle, including radar-based ascertainment of driving-environment data with the aid of an ascertainment device of the vehicle, comparing the ascertained driving-environment data to corresponding data of the digital map, and Verifying a validity of the digital map for the case when the driving-environment data, ascertained based on radar, coincide to a defined extent with the data of the digital map.

Abstract: A method and an associated system for vehicle localization are described. The system includes a first sensor unit for determining a relative movement of the vehicle in relation to at least one feature in the vehicle surroundings and a second sensor unit for detecting radar data of the vehicle surroundings. The system also includes a memory for storing a digital map, a localization unit, which is configured, for ascertaining a preliminary position indication, to localize the vehicle in the digital map based on the relative movement determined by the first sensor unit, and a position determination unit, which is configured to compare the radar data detected by the second sensor unit with the digital map while taking the preliminary position indication into account, and to determine a position of the vehicle based on the comparison.
